Hi All.
Long time lurker, first time poster.
I have a new to me Shenyang lathe with an Oi-TC controller.
I'm trying to get a bar puller set up.

The code below does all as expected until line N134.
The chuck closes and the machine stops.
'Chuck closed' light is on and there are no alarms.

Any help would be much appreciated.
Cheers
Phil

Phil,

My Fanuc use a decimal point for dwells. IE: 1.5, 2.0

If I used 2000 that would be 2000 seconds. Which would be 33.33 minutes..

Might try a P2.0

One note: mine use a X1.5 not P1.5 also. But they are OTC's. Not

hello, i can't help with your code

i wish to recomand you paying attention to axis loads when using bar pullers

if springs are too hard, or if alignment is not ok, etc, then extra axis load will appear, and maybe also sudden effort peaks

if possible, monitor axis load during the puller sequence, otherwise, you may speed ( considerably ) up axis wear

if conditions are not ok, is possible to have a setup when puller sequence requires an effort like for drilling a big hole, going over 100% load

i see that you use G01 when puller is climbing to, respectively pulling out, from the material; this is ok

even if your initial setup looks fine, thus movement is smooth, load is low, etc, in time, missalignments may appear, uneven wear on puller arms may appear, small chips may get inside the puller mechanism, etc, and all these will increase the axis load / kindly

controls usually are looking ahead
N138 G28 UO. change the O to a 0

Hi All.

Many thanks for your thoughts.
My machine needs "x000" for timing, and is working as expected. A P2.0 alarms out to an illegal decimal place.
Changing the G28 UO. to U0. didn't affect things.

My cnc service mate believes the controller is looking for a signal to confirm the chuck is closed when in program mode. Apparently this is different to the signal when using the controller button or foot switch and may be associated with a bar feeder setup. My machine does not have a bar feeder capability.

The ladder points to a 'low coolant level' which I assume is a typo.

I'm hoping we tweak the ladder to point the controller at the same sensor it looks at in manual mode.

Cheers
Phil
